8.6.3 S(4/4/4) Configuration

The S(4/4/4) (i.e., 4 carriers x 3 sectors) configuration requires two combined
cabinets, and the RLDU should receive two signals and process each signal in 1-4
modes. The following shows the configuration of the boards or modules.
Baseband boards: 1 BCIM, 2 BRDM, 1-2 BCKMs, and BCPM can be configured
according to actual requirement.
